INVESTIGATIONS

Follow the claim to the evidence

Each investigation begins with a claim that is often presented as settled fact. We trace it to its original sources, examine what the evidence actually shows, and distinguish observed findings from inference, modelling and opinion.

We set out the potential benefits, harms, limitations and unanswered questions in plain language. The purpose is not to prescribe a conclusion, but to give readers the information needed to reach their own judgement.
